To all whom it may concern.-

Be it known that 1, WILLIAM SIMMoNDs, of Yonkers, in the county ofWestchester and State of New York, have invented a new and ImprovedWVindow-Blind Fastener, of which the following is a full, clear, andexact description.

The object of my invention is to provide a cheap, practical, andconvenient device to be applied to window-blinds, whereby they may belocked in closed position or held partially open; and the inventionconsists of the construction, arrangement, and combination of parts,allas hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a front elevation of a windowframe and window-blinds havingmy invention applied thereto, showing one blind closed'and locked, theother held partly open. Fig. 2 is a sectional plan view of the same.Fig. 3 is a perspective view of one form of the fastener removed, andFig. 4 shows a modified form of fastener.

The invention will first be described in con nection with the drawings,and then pointed out in the claims.

Each blind A is provided with an ordinary spring-fastener, B, formedwith a hook, a, and opening or eye I). A. staple, O, is driven in thewindow-sill for fastening each blind, the hook abeing adapted to engagewith the staple, asshown at the left in Figs. 1 and 2. Upon each stapleis placed loosely the fastening device D, formed with a projection, d,upon its under surface to enter the eyeb of the fastener (N0 model.)

B, for holding the hooks a thereof in firm engagement with the staples.The device D is also formed with an upwardly-projecting knob, d, forconvenience in operating the de vice, and at the right in Figs. 1 and 2this knob is placed at an angle in the device, and inthis form of deviceand in that shown in Fig. 3 the same is formed with a second projection,d", at the outer end to enter the eye of the spring-fastener, as shownclearlyin Fig. 2, for holding the blind partly open.

In the form of device shown in Fig. 4 the same is composed of a shortbar provided with a centrally-placed wire hook, h, for attaching it tothe staple, while in Figs. 1, 2, and 3 the device is cast in one piece,with an orifice, i, to be placed upon the staple before the same isdriven into the window-frame.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
